A
Portable oil extractor is a device which is used to remove the oil
from a vehicle's engine without the need for getting under the vehicle
to remove the oil drain plug.

Portable oil extractors consist of a flexible tube which can be
inserted into the engine, a pump for drawing out the oil, and a
reservoir for holding the oil. Some portable oil extractors come
without a reservoir in which case a separate container must be used.

Portable oil extraction units are often used to remove the oil from
inboard boat engines where there is limited space underneath the
engine.
